Regarding return policies, we too learned the hard-way, from Lasten Tarvike. We bought a pram, bassinet and a car seat from them, and we fell for the the rather aggressive-sweet sales pitch,

i.e. last few pieces in stock from 2007, only difference to 2008 was colour etc.
Very soon we realised that items of similar quality and better colour and 2008, especially the car seat was at least 50%, if not 70% cheaper at other locations. We called back and they said they had no return policy, even though the item was unopened - i.e. in its original packing. Not even the cardboard was opened. At €300, that was an expensive lesson.
Now, I make it a point to ask (
after all the sales pitch etc., when I think I've let them know that I am really interested and just about to hand over my income) about their return/repair policies etc. right before handing over my credit card, and if the answer is not to my satisfaction, I walk - simple as that.
So, yes, in that sense, I was committed to buying, I was going to buy it, but then changed my mind, a second before, simply because I had a right to - like they have a right to no returns policies.
But a question on this topic: What is the policy? Do they have to display a policy or no? In the US, e.g. if they don't have a refund policy, there is a rather prominent statement saying so. Should they not have something displayed here? I've seen a lot of shops that do display it rather prominently here too, i.e. fourteen days with receipt etc.
Kind regards.
